Ulsan City in South Korea marked a significant milestone by installing the country's first hydrogen charging station for hydrogen trucks at Korea Zinc Plant 1 in Ulju-gun. The station, constructed at a cost of 6.05 billion won, has the capacity to charge 12 hydrogen trucks per hour with a charging scale of 55 kg per hour. This pioneering move allows for mass charging without interruptions, utilizing hydrogen supplied through pipes. The approval by the Ministry of Trade, Industry and Energy for an unregulated demonstration paved the way for the installation, which is a crucial step towards promoting hydrogen mobility. Korea Zinc is currently operating a fleet of five hydrogen vehicles, comprising a 3-ton hydrogen truck by Doosan Bobcat and four 5-ton hydrogen trucks by HD Hyundai Site Solutions. These trucks have undergone rigorous verification, including durability tests and pitching capabilities. The hydrogen trucks offer several advantages over traditional diesel vehicles, such as zero carbon emissions, a 16% reduction in fuel costs, and quick 3-5 minute charging times. Park Ki-duk, CEO of Korea Zinc, expressed the company's commitment to actively contribute to expanding the usage of hydrogen in the low-carbon era. This installation marks the beginning of a shift towards cleaner energy sources in the heavy equipment sector at industrial sites in Ulsan.
